I've wrote a post about clutchless if you have questions. See RAVolt.com <br><br>According to EV America, the brush timing in an Advanced DC motor is specifically setup for EVs to only go in 1 direction. Reversing the motor is a bad idea. I won't restate that AC is different.

Hi John,<br><br>With electric you don't "need" a clutch. That is because the motor<br>doesn't idle, so the transmission input shaft is not spinning when you<br>are stopped. You just stop and slip it in reverse. Just don't try to
<br>put it in reverse while in motion.<br><br>It is also possible to reverse the motor, but if you have a manual<br>transmission I would go with that. Reversing the motor requires<br>reversing the field winding polarity. That is done with four
<br>contactors. The down side of that is extra high power parts and motor<br>brush timing issues.<br><br>Ken<br><div><div></div><div class="Wj3C7c"><br><br>-----Original Message-----<br>From: loopcat <<a href="mailto:loopcat@yahoo.com">

<br>manual transmission without the clutch, how is it<br>possible to shift to reverse? I have see some<br>conversions that use a electric switch to control<br>direction, Is the direction changed by the<br>motor-controller?
